10月22日北美托福考试作文机经:
阅读材料讲wetland 里面鬼火 will-o"-the-wisp 的原因,三个:1)埋在里面的有机体释放出可燃的气体;2)是一种electric spark;3)一种能发光的蘑菇附着在鸟身上.
听力反驳:1)可燃气体是不动的,但是人们看见的鬼火是move around;2)electric spark是在wetland下面的rock中生成的,不会跑到上面来;3)这种蘑菇的发光物质在体内,要broken into pieces 才有用,但是这种物质不sticky,所以会从鸟身上掉下来.
大作文:the advice from our grandparents have no use for their grandchildren because the world changed a lot during the past 50 years.
